Parasitoids of the genus Trichogramma are oophagous micro-hymenoptera widely used as biological control agents. My PhD is about the phenotypic characterization of this auxiliary's movement strategies, specifically the movements involved in the exploration of space and the search for host eggs. These phenotypes have great importance in the life...

Nous présentons ici une méthode simple et pratique de comptage automatique permettant de dénombrer des oeufs et quantifier le taux de parasitisme chez les parasitoïdes oophages, en particulier ceux du genre Trichogramma. La méthode repose sur l'analyse d'images en couleurs, combinant analyse discriminante et segmentation, afin d'être adaptable...

Bridging behaviour and spatial propagation in minute insects: the double-spiralmethod and image analysis pipelineMélina Cointe, Vincent Calcagno, Ludovic Mailleret, Mathias Launay, Victor Burte, Guy PerezStudying what is difficult to observe, has always aroused the curiosity of human beings and fosteredmethodological innovations. Minute insects...

Abstract Background Understanding how behavioural dynamics, inter-individual variability and individual interactions scale-up to shape the spatial spread and dispersal of animal populations is a major challenge in ecology. For biocontrol agents, such as the microscopic Trichogramma parasitic wasps, an understanding of movement strategies is...

Minute insects such as parasitic micro-wasps have high basic and applied importance, for their widespread use as biocontrol agents. Their dispersal is a phenotype of particular interest. Classically, it is evaluated using field releases, but those are time consuming, costly, and their results highly variable, preventing high-throughput and...

Trichogramma are parasitic microwasps much used as biological control agents. The genusis known to harbor tremendous diversity, at both inter- and intra-specific levels. The successful selection of Trichogramma strains for biocontrol depends on characterizing the existing diversity in this group, especially regarding oviposition performance and...
